MC-2 is a tube type MC head amp with no special requirements. (MC-1 has special conditions.)

 

<Reasons for creating a tube head amp>

This MC-2 head amp is a tube type, and the audio signal does not pass through resistance.

I think that the parts that degrade the sound quality of an audio system are transistors, transformers, and resistors.

The step-up transformer has a good SN ratio and is the most common MC step-up product in the world.

However, a phase shift occurs between high and low frequencies as a characteristic of transformers.

Considering the phase shift, I feel the limit of the step-up transformer is 20~20kHz.

It was difficult to achieve a high SN ratio with a vacuum tube, so I had a hard time making the MC-2, but I was finally able to commercialize it.

MC-2 has no phase shift and almost no frequency limit.

All products of Miyajima Laboratory are designed so that audio signals avoid these three as much as possible.

By avoiding these three, a Hi-Fi audio system with realistic sound quality is completed.

The MC-2 is the ideal MC head amp.

 

  • Both low impedance cartridges and high impedance cartridges are supported.
  • Receive with a 50k ohm load impedance amplifier.

 

<attention>

  • There is a slight white noise of the tube at high volume.
  • The MC-2 occasionally receives broadcasts and illegal radio in wooden buildings, but not in steel buildings.

Description of each part


Connect the DIN cord from the main unit to the power supply.

Attach the power cord and connect it to the outlet.

Connect the phono cable to the IN of the main unit, and connect the OUT to the MM input of the preamp.

There are two INPUTs, A and B, so please use the switch on the side.

Please turn on the power switch

 

There is an input impedance selector switch on the front upper part of the main unit.

Choose a value approximately ten times the impedance of the cartridge. Select 150 ohms for Miyajima-lab stereo cartridge and 51 ohms for monaural cartridge.

By setting it to ∞, the impedance of the cartridge can be used as the input impedance.

If you don't know the impedance, choose 150 ohms.
